+
+## Quick Start
+
+### Prerequisites
+
+- Python 3.11+
+- Node.js 18+
+- PostgreSQL or MySQL (for database backups)
+
+### Backend Setup
+
+```bash
+cd backend
+python -m venv venv
+source venv/bin/activate  # On Windows: venv\Scripts\activate
+pip install -r requirements.txt
+
+# Run the server
+uvicorn app.main:app --reload --port 8000
+```
+
+### Frontend Setup
+
+```bash
+cd frontend
+npm install
+npm run dev
+```
+
+### Production Build
+
+```bash
+cd frontend
+npm run build
+
+cd ../backend
+uvicorn app.main:app --host 0.0.0.0 --port 8000
+```
+
+## API Documentation
+
+Once the backend is running, visit:
+- Swagger UI: http://localhost:8000/docs
+- ReDoc: http://localhost:8000/redoc
